Most of these barbs are bunk. Yes, Mr Obama favours trying Khalid Sheikh Mohammed, the alleged mastermind of September 11th 2001, in a civilian court. But that is not a sign of weakness. Several terrorists were successfully prosecuted in civilian courts under George Bush. And though Mr Obama is willing to admit his country’s failings, he is quite ruthless about blowing its enemies to scraps. American drones fired missiles at suspected Taliban and al-Qaeda leaders in Pakistan’s tribal areas 55 times last year, killing hundreds of jihadists and who knows how many civilians. This year, the killing has accelerated; so far more than a dozen strikes have been reported. Mr Obama orders assassinations at a far brisker pace than George Bush ever did. For some reason, his habit of blowing up alleged terrorists and bystanders from the air causes less global outrage than the smothering of a lone Hamas operative, allegedly by Israel, in a hotel room in Dubai. But whether you think it justified or not, it is hardly evidence that the president is “against killing terrorists”.Emphasis mine.
The whole thing is worth a read: Is Obama Tough Enough? The essay ends with a note about Iran.
